Funniest YouTube Video Ever

This is the funniest YouTube video I have ever seen.  Ever.

Once, in high school, Shana played a little piano recital in the band room for our English class.  It was silent in there, except for the crashing hilarity of her perfectly-timed wrong notes, and my muffled, yet very obvious, laughter.  I don't know what got into me.  I wound up apologizing to her, my teacher, the whole class.  I couldn't stop laughing.  I felt horrible, I knew the stakes were high, but...

In this guy's case, he knew his career was in the balance, and couldn't stop.  Rarely does reality eclipse Monty Python.
